EARTHQUAKES

Lowercase earthquake in a name:Loma Prieta earthquake.

In recent years seismologists have abandoned the familiar Richter
scale for measuring earthquakes and now use the more precise
moment-magnitude scale, which measures the total energy released by
quakes:a magnitude 6 quake (no hyphen)recording 7.12.5 to 3
magnitude tremor (do not use decimals with round numbers)
